Higher activity and/or fitness are associated with higher incidence rates for cancer of the colon and breast. In general, exercise does not provoke cardiovascular events in healthy individuals with a normal cardiovascular system. Higher activity and/or fitness levels are associated with lower mortality from coronary artery disease. Based on meta-analyses, cardiovascular and all-cause mortality are reduced in patients with post myocardial infarction who participate in cardiac rehabilitation exercise training.

There are two firms producing identical seltzer water, each with a constant marginal cost of 3 with no other associated costs. Let the market demand for seltzer water be given by Q = 168 − 4 min{p1, p2}, where Q = q1 + q2 is the total market quantity (number of cases) and p1 is firm 1’s price and p2 is firm 2’s price. Suppose that the firms split the market evenly when p1 = p2. (a) Suppose the firms act as Bertrand (price) competitors. (i) What is the equilibrium price set by each firm? (ii) What is the equilibrium quantity sold by each firm? (iii) What are the equilibrium profits for each firm? (b) Suppose that, prior to competing in prices, the firms can choose their capacities. They do so simultaneously and independently, but know each other’s capacity prior to competing in prices. (i) What capacity should each firm invest in if they wanted to maximize joint profits? Why do these capacities not constitute a Nash equilibrium? (ii) What capacities would each firm choose in the Nash equilibrium? What is prevailing market output, market price, and each firm’s profits in this equilibrium?

QUESTION 3. A 1.25 L buffer solution is prepared from 0.35 M HClO (Ka = 2.9 x 10-8 ) and 0.75 M NaClO. Use this information to determine: a) The pH of the buffer solution. b) The pH of the buffer solution after a volume of 25.0 mL of 1.50 M HCl is added to the 1.25 L buffer solution in Question 3a). c) The volume (in mL) of a 11.5 M HCl solution that would be needed to be added to the buffer solution in Question 3a) to just cause this buffer to collapse. (This question is a bonus 3 Marks) Hint: In all cases ignore the contribution of hydrogen ions from water. (Approx. 10 marks (excluding Question 3 c))
